Diastolic dysfunction of treated patients correlates with the dose-volume of heart irradiated. (A–D): Averages of Dn (Gy) of heart (A) and LV (B) and averages of Vn (%) of heart (C) and LV (D) in patients with normal baseline left ventricular diastolic function.
Abbreviations: Dn, minimum dose that reached at least n percentage of volume; LV, left ventricle; Vn, percentage of volume receiving at least n Gy.
